Nrog rau kev nce siab ntawm kev txawj ntse, cov kws tshawb fawb hauv North America thiab Europe tau ua tiav qhov kev vam meej hauv kev tshawb fawb thiab kev txhim kho kev kho mob.Ntawm lawv, kev txawj ntse prostheses (robot prostheses) tau nyiam ntau yam.Ib qho tseem ceeb ntawm AI prostheses yog lub zog tswj chav tsev.Cov tshuaj prosthesis ib txwm txhawb tus neeg siv nyob rau hauv ib qho kev ruaj khov, yog li tus neeg siv lwm cov ceg thiab lub cev feem ntau yuav tsum tau koom tes nrog cov tawv prosthesis kom ua tiav qhov kev txiav txim.Tsis tsuas yog lub peev xwm txav tau txwv, tab sis kuj yog qhov kev txav tsis sib haum xeeb.Nws yog ib qho yooj yim rau kev poob thiab tsim cov teeb meem thib ob, tsim kev nyuaj thiab nyuaj rau cov neeg mob.Sib txawv ntawm cov khoom siv dag zog ib txwm muaj, cov neeg siv khoom siv dag zog tuaj yeem muab cov neeg siv khoom siv ntau dua li kev txhawb nqa kev sib npaug raws li kev hloov pauv ntawm txoj kev thiab kev txav mus los, tso cai rau lawv ua haujlwm ywj pheej thiab txhim kho lawv lub neej zoo heev.

Raws li kev txheeb cais, muaj tsawg kawg yog 300,000 amputees hauv Asmeskas.Hauv Suav teb, muaj 24.12 lab tus neeg xiam oob khab, ntawm 2.26 lab yog cov neeg tsis taus, thiab tsuas yog 39.8% tau siv cov khoom siv dag zog.Kev txheeb cais nyob rau hauv ob xyoos dhau los qhia tau hais tias nyob rau hauv Tuam Tshoj qhov nruab nrab txhua xyoo ntawm cov tshiab amputations yog hais txog 200,000 vim hais tias ntawm tsheb sib tsoo, muaj xwm txheej, mining xwm txheej thiab kab mob.Tus naj npawb ntawm amputations vim ntshav qab zib yog nce sai heev.Prosthetic libs kuj yuav tsum tau hloov thaum lawv muaj hnub nyoog.Tsis tas li ntawd, cov neeg mob uas muaj cov leeg tsis muaj zog, cov leeg nqaij atrophy, lossis hemiplegia kuj xav tau kev pab kho mob xws li exoskeletons los pab lawv sawv lossis txav mus ntxiv.Yog li ntawd, ntau npaum thiab txhim khu kev qha ntse prosthetics thiab ntse exoskeletons muaj kev xav tau kev lag luam zoo thiab qhov tseem ceeb ntawm kev sib raug zoo.

Txhawm rau kom paub txog kev tswj xyuas lub zog ntawm cov khoom siv ntse ntse, 6 DOF quab yuam sensors yuav tsum tau paub txog kev hloov pauv hauv txoj kev hauv lub sijhawm tiag tiag thiab tswj xyuas qhov loj ntawm lub zog.Qhov nyuaj ntawm txoj kev, qhov sib txawv ntawm kev ua thiab kev txwv kev sib koom ua ke muab cov kev xav tau siab heev ntawm 6 DOF quab yuam sensors.Tsis tsuas yog nws yuav tsum ua kom tau raws li qhov xav tau ntawm lub zog thiab lub sijhawm, tab sis kuj yuav tsum hnav thiab nyias.Cov neeg siv tau hais tias tom qab kev tshawb nrhiav, lawv pom tias, ntawm kev ua lag luam, tsuas yog SRI M35 ultra-thin series 6 DOF quab yuam sensors tuaj yeem ua tau raws li tag nrho cov kev cai no.
M35 series suav nrog 18 qauv, tag nrho cov uas muaj tsawg dua 1cm tuab, thiab qhov tsawg tshaj plaws tsuas yog 7.5mm tuab.Qhov hnyav tag nrho yog tsawg dua 0.26kg, thiab lub teeb tshaj plaws tsuas yog 0.01kg.Non-linearity thiab hysteresis yog 1%, crosstalk tsawg dua 3% thiab tau tsim nrog nyiag ntawm cov ntawv hlau hlau strain ntsuas tshuab.Qhov kev ua tau zoo ntawm cov nyias, lub teeb, compact sensors tuaj yeem ua tiav vim yog 30 xyoo ntawm kev tsim qauv ntawm SRI, pib los ntawm lub tsheb kev nyab xeeb kev sib tsoo dummy thiab nthuav dav dua.Cov thev naus laus zis tam sim no tau siv rau hauv kev tshawb fawb thiab kev txhim kho ntawm cov ntse ntse prosthetics los tiv thaiv kev nyab xeeb ntawm ntau tus neeg.

Tsis tas li ntawd, tus nqi rau SRI sensors yog qhov sib tw heev piv nrog cov los ntawm lwm cov tuam txhab loj zog sensors.Nrog nws cov kev siv zog muaj zog thiab tus nqi pheej yig, cov khoom siv SRI uas tsis tshua muaj txiaj ntsig tau nthuav tawm los ntawm cov lus ntawm lub qhov ncauj thiab nyiam heev los ntawm cov chaw soj ntsuam kev kho mob saum toj kawg nkaus thiab kev lag luam kws kho mob prosthetics.Hauv 7 xyoo dhau los, bionics thiab biomechanics cov kws tshawb fawb thiab cov kws tshaj lij los ntawm Tebchaws Meskas, Tuam Tshoj, Canada, Nyiv, Ltalis, Spain thiab lwm lub tebchaws tau siv SRI ultra-thin sensors rau kev tshawb fawb tshiab, luam tawm ntau cov ntaub ntawv kawm thiab ua tiav zoo kawg li. kev vam meej.
Hauv tsab xov xwm tom ntej, peb yuav qhia txog daim ntawv thov ntawm SRI M35 ultra-thin series hauv kev kho mob kho mob.Nrog rau cov kev tshawb fawb tshiab tshaj plaws ntawm kev txawj ntse prosthetics thiab ntse exoskeletons luam tawm hauv Nature thiab IEEE cov rooj sib tham cov ntawv xov xwm.Nyob twj ywm!
